Paint stops when switching desktops

Anybody seen this on macOS Tahoe? I’m running a juce app, I have another app running full screen on another desktop, I swipe over to it and then when I come back my juce app appears locked up. No more painting, but the audio engine is still running.

To reproduce:

Unfortunately I wasn’t able to reproduce the issue the only difference I can see is that I’m running Tahoe 26.2.

Some things I tried

  • Running debug and release builds
  • Running with and without a debugger attached
  • Running with and without an external monitor attached (and tested on both monitors)

I just upgraded to Tahoe 26.3.1 and it still does it. I’m running a single 5K2K monitor and debugger attached. I’ll see if I can reproduce on another machine.
